TAV2-501+ 50Ω SMD Low Noise E-PHEMPT RF Amplifier Mini-Circuits TAV2-501+ 50Ω SMD Low Noise E-PHEMPT RF Amplifier is an ultra-low noise, high IP3 transistor device that is manufactured using EE-PHEMT technology enabling it to work with a single positive supply voltage. Measuring 2mm x 2mm, the 8-lead MCLP packaged component provides low inductance, repeatable transitions, and excellent thermal contact to the PCB. Enhanced linearity over a 0.4GHz to 3.9GHz frequency range makes the TAV2-501+ ideal for us in driver amplifiers for complex waveform up converter paths or divers in linearized transmit systems. This single device covers many wireless communications bands including cellular, ISM, GSM, WCDMA, WiMax, WLAN, and more.
